Abstract

With the cooperation of many research institutes and railway companies, the next generation high speed train is under development for many years. To confirm the safety requirement of the developed high speed train, multibody dynamic analysis is implemented. Through this analysis, railway derailment and lateral guiding force simulation was evaluated according to UIC code 518 OR for international railway vehicle. Test results were compared by limit value of safety criteria. Safety evaluation results, according to international standards, would provide basic reference data of ensuring safety speed and track radius curve. The safety of the train at the maximum speed is verified by numerical analysis results.

차세대 고속열차(HEMU-430X)는 연구 지원과 많은 연구 기관의 노력으로 다년간 개발 중인 한국형 고속열차이다. 열차 모델을 다물체 동역학 해석 모델로 개발하여 차량-궤도 안전성 해석을 수행하였다. 이를 통해 국제 철도 안전 기준인 UIC code 518 OR에 따라 탈선 평가와 횡압의 제한 값을 확인하였다. 국제 기준에 따른 안전성 평가를 통하여 앞으로 본선 운전에 필요한 안전 확보 기본 자료를 생성하였으며 최고 속도에서의 안전성을 확인하였다.
